Water tank cleaning in South Obhur Jeddah

South Obhur lines the southern shore of Obhur Creek, a coastal expanse of villas, chalets, rest houses, resorts and apartment blocks. Year round high humidity and salt laden air come with the location. Chalets and rest houses sit empty for months, leaving their tanks open to unchecked algae and bacterial growth. Modern villas and resorts consume water heavily and accumulate sediment fast.

Why the job is different in South Obhur

Tanks here endure continuous pressure from humidity, salt air and heavy consumption. Some sit idle or nearly empty for months when chalets are closed, leaving standing water to foul. The method is set out in full on what Water tank cleaning involves.

The first reason

Closed chalets leave tanks defenceless against fouling

Chalets and rest houses sit locked for weeks or months. A stagnant tank in humid coastal air becomes a perfect nursery for bacteria and algae. The water may turn black or red as microbial blooms explode.

The second reason

Modern villas with high water draw speed up sediment accumulation

Luxury villas feature irrigated gardens, pools and multiple bathrooms. Heavy use lifts floor sediment and pipe scale upward constantly. The tank in this pattern needs frequent cleaning to stay ahead of the load.

The third reason

Salt and humidity corrode tanks rapidly on the coast

The coastal location means humidity over 80 per cent year round and airborne salt. Metal tanks rust fast and concrete cracks. Small leaks can enlarge into major weeps within weeks.

Landmarks of South Obhur

South Obhur runs along the South Obhur Corniche from Obhur Creek westward to King Abdulaziz Road and Madinah Road eastward. We reach tanks via seafront streets or interior roads depending on whether the villa or chalet sits oceanside or inland.

Before treatment

The condition of the tank decides the method

A coastal district separated from North Obhur by Obhur Creek, running from the seafront waterline to Madinah Road, lined with the South Obhur Corniche and densely built with tourist and residential buildings.

Fine brown sediment beneath shallow water

The layer on the floor

Sediment here may contain sea salts, iron and algal matter. In idle tanks, algae may dominate the floor layer entirely.

Light and algae

Algae grow explosively in stagnant water, humid air and heat. Empty or nearly empty tanks are perfect breeding grounds.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall deposits run red, green or black depending on algae and bacterial species present. Deposits can worsen rapidly in closed chalets.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Cracks can appear from salt corrosion, humidity and heat acting together. Even relatively new tanks may develop small weeps.

The lid of a water tank on a building roof

The lid and the access hatch

Lid and vent seals may not be airtight on new chalets. Salt air can enter directly.

The vent hole admits humid salty air, and the overflow may discharge recycled water from gardens or bathrooms.

How we work

1
Inspect before the drain

Tank type and material, the condition of the lining, the depth of the sediment, the lid and the vent, and where the drained water will go. We agree the window without supply before anything is opened.
2
Drain, then lift the sludge

The water leaves through the outlet, then the layer beneath it is taken out by hand and by suction. That layer is the reason for the visit, not the water that ran out ahead of it.
3
High pressure wash

Walls, floor and the joint where they meet, with a brush wherever the film resists, then the wash water is taken out completely so nothing we lifted settles again.
4
Disinfect and put back in service

Disinfectant over every internal surface, left for its contact time and then rinsed out, followed by the refill, a first draw off at the taps, and a report on what was inside the tank.

What water tank cleaning includes

An inspection before the valve

Tank type, lining condition, depth of sediment, lid and vent, recorded before any water leaves.
Full drain and sediment removal

The water through the outlet, and the layer below it by hand and by suction until the floor itself is showing.
Pressure washing walls and floor

High pressure across the surfaces and corners, and a brush on anything water alone will not lift.
Disinfection after the wash

A disinfectant intended for drinking water tanks, named to you before it is used, left for its contact time and then rinsed out.
Refill and the first draw off

We refill, run the taps so the new water moves through the pipework, and tell you when it is ready to use.
A report and the next date

What was inside the tank, anything on the lid or the lining that needs repair, and a sensible date for the next clean.

What is different about Obhur Sub-Municipality

Obhur sub-municipality runs along Jeddah's northern shoreline from Al Shati up to Obhur Creek. It mixes large villas and gated compounds with busy commercial spines of restaurants, cafes, markets and hotels. Sea humidity is high for most of the year and salt laden breezes keep timber and render damp, while irrigated gardens and lawns surround the corniche and the villa plots. Standing irrigation water, dense planting and food waste from the hospitality strip suit cockroaches, mosquitoes and ants, and the chalets and rest houses scattered along the creek stand empty for long spells, which lets insects and rodents settle undisturbed.

Questions about this district

The chalet was closed for three months and the water went black when opened. What caused it?

Stagnant water in humid air breeds bacteria and algae explosively. Black water means dense microbial bloom. Deep cleaning and strong disinfectant are essential before the water is safe to use.

The new villa tank needs cleaning nearly every month. Is this normal?

Heavy consumption can cause fast sediment accumulation if pipes are older or the inlet filter is weak. Coastal humidity speeds algae growth too. Monthly cleaning may be necessary at this usage rate.

The villa tap runs red water and smells foul. What is happening?

Red colour can come from iron oxide or certain algae types. Foul smell usually means bacterial bloom. Tank cleaning and inspection of metal pipes is necessary.

Do empty resorts and chalets need different cleaning than occupied villas?

Yes, chalets awaiting reopening need deep cleaning and strong disinfectant beforehand. Occupied villas need routine cleaning matched to water consumption.

The tank sits on an exposed rooftop and is very hot in summer. Does heat affect water quality?

Heat accelerates algae and bacterial growth. Exposed tanks can reach 50 Celsius in summer. A shade structure and frequent cleaning are essential.

The rest house tap smells of sea salt although the building is new. Why?

Salt can enter through unsealed vent holes or from direct sea air exposure. New rest houses may have unsealed openings. Cleaning, disinfecting and careful inspection of all vents is necessary.

How much does water tank cleaning in South Obhur cost?

It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach South Obhur.
